feat(hub): embed agent images via Feishu upload + release v0.0.36

Materialize markdown image refs on agent finish: fetch/read bytes, upload
im.v1.image, and render native card img elements so remote image URLs no
longer trip Feishu content-security. Stream masks image URLs mid-run;
card failure falls back to plain text plus standalone image messages.

Docs: clarify im:resource covers outbound Agent image send.
